8.1.2. A plug - the main cylinder of coupling
THE GENERAL DATA

Hydraulic system of coupling

1. The tank of a working liquid
2. Consolidation
3. A hydraulic hose
4. The main cylinder of coupling
5. A lock nut
6. A plug
7. A pin
8. 20 Н.м.
9. A clamp
10. The working cylinder
If the working cylinder has a plastic basic ring, slightly grease an external surface of a ring before installation
11. A washer
12. 25 Н.м.
13. The valve for prorolling
Open only for prorolling
Use the tool for prorolling of brake system 1116
The maximum working pressure: 25 bar
14. A connector, 15 Н.м.
15. A delivery tube (with a pressure head hose)

The prevention

Do not squeeze out a coupling pedal at the removed working cylinder.


Before adjustment of a plug of the main cylinder of coupling make sure that the plug of the amplifier of brake system is adjusted according to necessary height of a pedal of a brake.

The uncoupling device

1. The working cylinder of coupling
At installation move the lever to insert a bolt
2. 25 Н.м.
3. A pusher
Grease the end
4. Squeezing the bearing
Wipe, do not wash
If publishes noise, replace
5. A bolt with a head under a face key, 35 Н.м.
Self-stopped, always replace
6. Squeezing the lever
Wipe, do not wash
If publishes noise, replace
7. A returnable spring
Fix on the squeezing lever
8. The directing plug
9. An epiploon of an entrance shaft
Take from the plug tool VW 681
Insert the tool 4450
10. Ring consolidation
Always replace
11. A washer
Smaller diameter (the bent party) is directed to directing plug
12. A raspornaja detail
13. A core with a spherical tip (25 Н.м.)
14. A transmission

Before installation of a disk of coupling clear шлицы an entrance shaft, and also nave teeths if the disk is used repeatedly, from traces of corrosion and the greasing rests. Put very few greasings (G 000 100) only on шлицы an entrance shaft. Establish a disk on a shaft and move forward-back while the disk nave will not slide easily. Remove all superfluous greasing.

Adjustment

PERFORMANCE ORDER
1) check up adjustment of a plug of the amplifier of brake system: and = 269.0 mm + 0.5 mm

The prevention

During measurement the pusher should be perpendicular surfaces of the amplifier of brake system.


2) adjust a plug of the main cylinder of coupling: and = 116.0 mm + 0.2 mm
3) the coupling pedal should be approximately on 10 mm above a brake pedal
4) the returnable spring should return a coupling pedal in a starting position
5) the coupling pedal should not concern an arm in a starting position

The prevention

The insufficient backlash between a pedal of coupling and an arm leads to premature deterioration.
